Im in love but hes muslim? any advice pleaseee?

He's Egyptian Muslim and im Christian. He wants to get married this week at a mosque but he said my family can't know nor his til time is right, and then we will get married legally. But hes a virgin and im not and hes still willing to marry me and since im going to be his wife he needs to give me large amount of money but he wants to buy me my own place and test things out. But im wondering y he wants to keep it a secret now =( is it cuz im not a virgin. Doesn't he need permission from my parents.??
